trade representative ron kirk is also on the mentioned list in terms of retiring. host: but none of those formally? guest: not official . host: has anybody said i'm sticking around? guest: that would be kind of unproforma but i think kathleen seebluss said she would like to stay because of the implementation of the health care law. no one announces that. they kind of get the word out there. there have been some talk about whether eric holder will retire but he told people he would like to stay for a year or certainly until september when we're likely to get a new f.b.i. director. host: if you're not leaving immediately at the end of the first term are you expected to stay for all four years of the second term or is there another dated where turnover occurs? guest: the way i understand it is if president obama has told people if they do stay he wants them to stay for at least a year because he doesn't want to spend all of his time filling these jobs. so the rule of thumb is if people are still in place at the end of january they'll probably stay for the entire year.
